GPU-Z will show if your GPU card has all the correct API's check marked and enabled. If one or more are not check marked that indicates the AMD driver wasn't installed properly. That is why I was asking to post an image of GPU-Z.
I have an Nvidia GPU card so there are 3 APIs that are checked marked that are strictly used by Nvidia and not by AMD.
Here is my GPU-Z:
DirectML may or may not be check marked for your card but all the others underlined should be check marked. Just to verify that everything is enabled to run your game.
Can you also post your Computer specs including PSU, Motherboard, CPU, GPU Make & Model plus Windows and AMD Driver versions installed?
Some times an underpowered PSU might cause freezes while under heavy loads like in a game.
Do you get any type of errors when the game freezes?
Also check Windows Device Manager for any errors.
Go to this website and double check that your Computer is able to run that specific game on your computer:

I would also try different settings in both the game itself and Radeon Settings to see if the freezes stops. Like first start off with minimum settings for the game. then go from there if no freezing.
